What is the only difference between gas and plasma?
Plasma particles have electric charges and gas particles do not.
Example of plasma is lightning or the Northern Lights.

Most homes today use __________ circuits because energy can flow along more than one path.
Most homes today use parallel circuits because energy can flow along more than one path.

Give two examples of potential energy.
Ex: A bird sitting in their nest, a book on the table, a computer sitting on a desk, a ball in someone's hand

Where do plants get the chemical energy that they need to grow?
Plants get the chemical energy needed to grow from the sun.

Give an example of a place you might find condensation.
Example: You might find condensation on the outside of an ice cold soda on a warm summer day. (The little water droplets that form are condensation because gas (air) has changed into a liquid (water))

Explain the difference between series circuits and parallel circuits.
Ex: Series circuits have only one path (meaning that one light switch would control your entire house or school).
Ex. Parallel circuits have more than one path along which energy can flow (meaning multiple light switches control your house or school)
